NUTRALOAF: This Revolting Food Is Used As Punishment In Prison

This Nutraloaf from a Vermont prison is made of whole wheat bread, non-dairy cheese, raw carrots, spinach, seedless raisins, beans, vegetable oil, tomato paste, powdered milk and dehydrated potato flakes.AP Photo/Andy DubackA now-defunct Philadelphia prison recently gave tourists a chance to taste prison food, and one of the items on its strange menu is used to punish prisoners: Nutraloaf.

A lot of U.S. prisons serve Nutraloaf — which is also known as "disciplinary loaf" — to inmates who misbehave, often three times a day. Nutraloaf recipes vary but often involve tomato paste, beans, and potato flakes baked into a flavorless brick served warm or at room temperature.

"Oh that's horrible. Oh my God," the Post-Star's Jon Alexander said. "I just see it as being a really great way to lose weight. It's the lack of flavor is what makes it so bad. It's like chewing on chalk." The Post-Star's Doug Gruse said the loaf smelled like a shoe.Glens Falls Post Star/YouTube

Prisoners have filed lawsuits over Nutraloaf but have been unsuccessful in getting it banned. In a handwritten lawsuit, a Washington state prisoner named Tommy Lynn Lewis called Nutraloaf "a little punishment block, not meant to eat."

The main impediment to getting that "punishment block" banned is its nutritional value. It has vegetables, protein, and roughly 1,100 calories.

"The Eighth Amendment [which bans cruel and unusual punishment] requires only that prisoners receive food that is adequate to maintain health," an Illinois appeals court ruled. "It need not be tasty or aesthetically pleasing."
